Constructors

CoreGestureDetector({Key? key, Widget? child, GestureTapDownCallback? onTapDown, GestureTapUpCallback? onTapUp, GestureTapCancelCallback? onTapCancel, GestureLongPressStartCallback? onLongPressStart, GestureLongPressMoveUpdateCallback? onLongPressMoveUpdate, GestureLongPressEndCallback? onLongPressEnd, GestureScaleStartCallback? onScaleStart, GestureScaleUpdateCallback? onScaleUpdate, GestureScaleEndCallback? onScaleEnd, HitTestBehavior? behavior, bool excludeFromSemantics = false, DragStartBehavior dragStartBehavior = DragStartBehavior.start, CanDragDownFunction? canHDragDown, CanDragDownFunction? canVDragDown})

Properties

behavior → HitTestBehavior?
How this gesture detector should behave during hit testing.
final
canHDragDown → CanDragDownFunction?
final
canVDragDown → CanDragDownFunction?
final
child → Widget?
The widget below this widget in the tree.
final
dragStartBehavior → DragStartBehavior
Determines the way that drag start behavior is handled.
final
excludeFromSemantics → bool
Whether to exclude these gestures from the semantics tree. For example, the long-press gesture for showing a tooltip is excluded because the tooltip itself is included in the semantics tree directly and so having a gesture to show it would result in duplication of information.
final
hashCode → int
The hash code for this object.
no setterinherited
key → Key?
Controls how one widget replaces another widget in the tree.
finalinherited
onLongPressEnd → GestureLongPressEndCallback?
final
onLongPressMoveUpdate → GestureLongPressMoveUpdateCallback?
final
onLongPressStart → GestureLongPressStartCallback?
final
onScaleEnd → GestureScaleEndCallback?
final
onScaleStart → GestureScaleStartCallback?
final
onScaleUpdate → GestureScaleUpdateCallback?
final
onTapCancel → GestureTapCancelCallback?
final
onTapDown → GestureTapDownCallback?
final
onTapUp → GestureTapUpCallback?
final
runtimeType → Type
A representation of the runtime type of the object.
